Mercedes-Benz CLA250 vs Audi RS3

What's the difference?

If you're after a hot hatch with a boot, you can't have one because it wouldn't be a hatch anymore.

What you can have is this little beast - the new, second-generation Mercedes-AMG CLA 45 S, a small coupe-style sedan sharing its high-performance DNA with the hot as bubbling lava A 45 S hatch.

Packing 300kW – that's just over 420hp – and 500Nm its 2.0-litre engine is claimed to be the most powerful series production turbo four ever made.

And Australian deliveries are scheduled for early 2020, with a likely price tag in the mid-$90k bracket.

Mercedes-AMG invited us to the car's global launch in Madrid, Spain, where we got behind the wheel on road and track.

Five-cylinder fury is still kicking!

Audi has just launched the mid-life updated version of its RS3 hatch and sedan in Australia.

With new looks inside and out, the German carmaker has also made a number of subtle tweaks under the skin via software updates. Thankfully, however, the five-cylinder beast lurking under the bonnet remains untouched.

As the viability of pure internal combustion engines in the hot hatch segment dwindles in the age of ever-tightening emissions regulations, will this be the last hurrah for the five-banger RS3?

Read along to see how this latest version stacks up.
